DETACHABLE COVER FOR COOKING FESSELS.

Application filed December 29, 1927.

The invention relates to cooking vessels of the pressure type, and it resides in such a vessel and a detachable cover therefor. The cover is held in closed position by means of clamps of peculiar construction, which clamps are mounted upon the cover in such relation that they may be made to engage the vessel, and so hold the cover in effective posi-' tion upon the vessel.

The clamps used in connection with the present invention, are of the type illustrated in Patent No. 1,641,681, granted September 6, 1927, to Ralph N. Kircher. In general, the formation of the vessel and its cover is quite similar to the type shown in the said patent.

My invention relates partitcularly to the clamp, and I have devised an improvement thereon which renders the same more nearly automatic in its operation, by the prevention and elimination of some movements heretofore performed manually in attaching the cover to the vessel and detaching it therefrom.

This result I achieve by forming as apart of the clamp, a stop which acts to support the hook in an outward position, upon an unclamping movement of the clamping lever, so that the hook is maintained clear of the vessel, to permit the removal of the cover without a manual operation of the hook.

In the construction illustrated, I utilize the clamping lever in its free position, as a counterbalance for the hook, the said lever causing the hook to pivot about the stop, and thus maintain the free end of the hook clear of the vessel.

Having thus outlined the nature of my invention, I will now describe the same specifically, and point out the novelty thereof in the appended claims.

In the accompanying drawing:

Figure 1 is a vertical transverse sectional view through the cooker and its cover near the diametral line, showing the manner in which my invention is applied thereto.

Fig. 2 is a similar view, but showing only the upper part of the vessel, with the hooks withdrawn from engagement with the vessel, and the cover slightly raised from the vessel, the view illustrating the position automati cally assumed by the hooks when the clamping levers are moved to their free position.

Fig. 3 is a plan view of a portion of the cover, with one of the clamps in the position illustrated in Fig. 2.

Serial No. 243,249.

Fig. 4c is a perspective View of the bracket forming a partof the clamp, and illustrating the formation of the stops for supporting the hooks, for the purposes of my invention.

In the drawing, the numeral 10 indicates the vessel, the vertical walls of which are surmounted by a ledge formed by bending outwardly the metal thereof, which is then turned upwardly in parallelism with the walls and finished with a bead, to give stabillty to the rim of the wall. The ledge referred to forms a seat, upon which rests the head at the lower edge of the flange depending from the cover 11, the construction in these respects being quite similar to what is shown 1n the patent before mentioned. I Attached to the cover atopposite points thereon areclamps, the purpose of which is to engage the cover 11 with the vessel 10 in such manner that a tight joint is effected. Usually four clamps, set quartering, will be applied to the cover. The clamps comprise a bracket 12 which is attached to the cover, a clamping lever 13 pivoted at 14 on the brackst, and a hook 15 pivoted at 16 t0 the clampmg lever 13 at a point intermediate the pivotal connection with the bracket 12 and its free end. In Fig. 1, the clamps are shown as in operative position, with the hooks in engagement with the underside of the ledge at the top of the vessel.

I provide the bracket 12 with a projection or pro ections 17, extending outwardly from the cover and in a posit-ion in which they will act as stops to limit the movement of the hook when the latter is in its disengaged position, and support the hook clear of the vessel. so that the cover may be readily removed from the vessel without manual operation of the hook.

In the prior patented construction, with the clamping lever 13 thrown outwardly into unclamping position, to release the pull upon the 1100 r, the hook remained with its free end in the vertical plane of the ledge at the top of the vessel. To remove the hook from that position, so that the cover might be raised, it was necessary to throw both the hook and the clamping lever back onto the cover, thisrequiring four manual operations in using the vessel. But by providing the projections or stops 17 in the position shown, the outward movement of the clamping lever 13 causes the hook 15 to pivot over the end of the stop 17, the weight of the clamping lever serving belvps theheek and dep e e pi otal point 16 into engege cnt vim the 11mm. side of the stop 1'7. The effect of this movemen!- i to a temeti slly withdrew the nd of hoo mitve dl into e position in which it is clezii' oi the vessel, and thus perlnit the cover to be telnofgfld with g 'e ete facility. i i i The automatic positioning of the hooks through the operation 01 the devices described, likewise serves to prevent interfe ence whe the cover ll is pleced upon the vessel. It is necesse 'y only to seat the cover upon the vess el ninl i'ol'nlfe the clnn iping levers l3 inivzn-d; l), Wiltl-l-UPOH the hooks sutonn tically assinne {he engaged positions sl'lon'n in Fig. l.

' The vessel will be equipped with lifting handles 18, attechcd at dpposite points on its sides. Bretenehly these handles will be whol- 1y below the operating" plane of thehooks so that in pliicing the cover npon the vessel, it may be a iitenged at random, as the handles will not intertero with the hooks, and so selectiye' pos t ing of the cover is avoided.

Having thus'desc cihed in invention, what I claim and desire to secure 5: Lette ts Patent of the United States, is

1'. A cooking utensil comprising a vessel having an upstanding side Well, e'cover thereter edeptedto be seated on the said side wall, .hQQhs pivoted on the cover and adapted to enthe vessel to secure the cover, upon the vessel, and means on the cover forinztinteinmg: the hooks 1- ay from the vessel when the QYQH is being applied to or removed from the vessel.

2 A cooking utensil comprising a vessel having an upstanding side ell, a cover adept-ed to be seated on the said side wall clamps attached to the cover for engagement with h v ss l f r retaining the cover: in position, such clamps comprising a pivqtelly mounted clamping lever, a hook pivotally connected thereto end adapted to engage the vessel to retain the cover in position thereon and n eg ns for holding the hooks away from the v s l Wh h evv is be n Wi lis-d t or remo tlls ef vem- 3. In a device for clamping it cover upon a. cooking vessel, it mounted on the said cover, a. clamping lever pivotally connected to the said bracket, a hook pivoted to the said leve and engegeable with the vessel to: clamping the cover thereto, and a stop on the cover adapted to support the hook clean the vessel while the cover is being applied thereto or removed thcirefioni. g

5. In a device for clamping a cover to cooking vessel, a bracket mounted on the said cover and having on ontive rd extension forming a stop, a clamping level: pivoted onthe said bracket, a hook pivoted to the said clamping level: at a point between the pivotal point and free end of the latter, the said hook in the outward movement of the clamping; lever being h ought into engagement with the aid stop so to maintain the hook clear of the vessel hile the cover is being applied to 9 removed therefrorn.

In testimony whereof, I have Signed lily name at West Bend, this th day of Decemher, 19.27. Y
